One of the objects of the present invention is to so construct and arrange the parts of a planter that substantially the whole machine can be made of metal, as steel, and therefore be stronger and more durable than those heretofore used.

I am aware that planters with metallic frames have been made or proposed; but to all within my knowledge have been incident objectionable features which I aim to overcome. I reduce the weight by simplifying the mechanism and dispensing with a number of the parts heretofore used.

The main ground-wheels are indicated by A A. The central main portion of the axle B is formed of hollow square steel tubing. At the ends it is secured to peculiarly-shaped spindles a, each formed with or secured to a flanged plate a, upon which the axle B can be firmly bolted or riveted. These wheel-carriers are shown in detail in Figs. 11 and 12, by reference to which it will be seen that the spindle a and axle-su pporting plate (7. are connected by a depending or downwardly-eurved web a, in the upper surface of which is formed a seat or recess a" to receive the lower edge of the adjacent side 0 of the frame 0. The plate a is provided with upwardly-extending side flanges (0, thus forming a seat into which the end of the axle B fits snugly, it being also connected to the plate a by bolts, as above described. Upon the axle B is supported the main frame O O. This also is made of steel, the wheel-supporting portion C being formed of a bar bent to provide the side pieces 0 c and the rear connecting part 0. At the front it is hinged to the runner-frame O, as at c a", the said runner-frame comprising a longer transverse angle-bar c at the front and a shorter angle-bar c at the rear, together with the brace-bars and the rearward-extending V- shaped brace formed of bars 0 for connecting the frame to the adjusting devices. The frames C C can be rocked relatively to each other upon the hinges at 0 by devices to be described. The tongue D extends across and is secured to the angle-bars 0 of the front or runner frame. At the outer ends the bars 0 c are connected by curved bars E, and the latter are also connected to the front bar 0 by curved arms E. Upon the frame thus provided the seed dropping apparatus is supported. It comprises at each end a box, as at F, in the bottom of which there is a seed -plate which for check-row planting is of the form shown at Gr, Figs. 13 and 16, it having pawl-teeth g' pusher g which forces the seed out of the apertures When the machine is used for check-rowing, the seed-plate is turned by a pawl or follower.

H is a lever pivoted to the outer end of the frame and carrying the fork H, with which the balls H Fig. 32, on the wire H intermittingly engage. The lever H turns a rockshaft 1, which is mounted in bearings 2' below or behind the frame-bar 0 Motion is transmitted through an adjustable link it h, the length of which can be varied to regulate the throw of the shaft I. The link is pivoted to a crank-arm H which is loosely hinged or mounted on the shaft I by an eye If, fitted thereon. On the shaft I there is rigidly secured a sleeve 1, which is cast with the sleeves I I. I The part I is connected with the part I by a bowed arm 6 and the parts I I are connected by an arm 2'. Then the crank-arm H is drawn forward, it engages with the arm 2' and shaft I is rocked; but it will be seen that the shaft can be rocked independently of the crank H as the latter is loose thereon, and the arm z' can swing forward without moving the crank-arm. (See Fig. 25.) When the shaft I is rocked forward, it throws forward the crank I, preferably formed with the sleeve I. At the upper end this crank is V hinged to a link J, which extends under the seedbox. It is formed with an offset j, on which is loosely pivoted the pawl J, adapted to engage with the teeth 9 on the seed-plate successively. At the end the bar J is hinged to the arm is of a bell-lever K, which is pivoted at k below the seed-plate and the other arm of which terminates in an expanded plate having the seed-passage k and the cut-off as shown in Figs. 18 and 26. It will be seen that when the balls H intermittingly engage with the fork H and press it backward the shaft I will be rocked forward, which results in advancing the seed-plate one tooth, and thereby brings one of the seed-apertures g into position to register with the conductingtube L; but' at this time, while the arm or crank I" of the shaft I is at its forward limit, the cut-off plate 70 intervenes between the upper end of the tube and the seed-plate, so that the charge of seed cannot leave the aperture g, and at this time the valve Z in the tube L is open, thus permit-ting the charge of seed delivered to said tube to drop from it. As soon as the ball H escapes from the fork H all the parts but the seed-plate are returned to their normal positions by the spring This is connected to the cross angle-bar 0 and to the crank I, secured to the shaft 1. When the shaft I and its connections are thus returned to their normal positions, the valve Z in the tube L is closed and the seed-passage k through the cutoff plate registers with the aperture g, permitting the charge brought forward by the latter to fall into the tube L, there to be retained by the valve Z until the fork H is again engaged by a ball H when the operations and movements above described will berepeated. It will be understood that the actuating devices of both seeding mechanisms will be similarly and simultaneously moved, and as the cranks H on both sides of the machine are loose in relation to the shaft it will be seen that the check-row wire can be used on either side without compelling the movement of the fork, its link, and crank on the other side. Mechanism of this sort enables me to dispense entirely with the slides and slide-guides which have been heretofore commonly used and to which has been incident much difliculty from friction, the loss 'of power, &c. In the present machine all the motions are vibratory, with the well-known advantage incident thereto.

With the check-row mechanism described there is provision also for a hand operation, use being made of the same rock-shaft and attachments and in such way as to be entirely independent of both check-rowers, which are, however, not removed from their places.

0 is a hand-leveradapted to bepivoted on either of the pivots 0, Fig. 16. It is connected by a link O to a swinging plate 0 Figs. 18 to 22, pivoted at 0 to a bracket 0 0* is a swinging lever also pivoted at 0. Its movements on its axis are limited by the plate 0 which has a slot 0 in which is seated a stud projecting from the lever 0*. The lever carries a link O which connects it to a crank 0*, projecting outward from shaft I. The plate 0 is limited in its swing by a projection 0 which impinges alternately on the opposite sides of the standard It will be seen that when the hand-lever O is moved in one direction it will through the link 0 raise the plate 0 and that the latter will draw upward the lever 0 When the lever O is in the upright position, it has rocked the shaft I the proper distance to move the pawl J and the other parts which actuate the seeding mechanism. As soon as the lever '0" passes the upright position it will be instantly carried down the length of the slot o because of the tension of spring 1", and this causes a quick rcturn'of the seed-actuating devices to their normal positions, and this is true in whichever direction the hand-lever O and the plate 0 are moved-that is to say, the lever O" rises to the vertical line under the pressure from the hand-lever, then instantly moves on and down on the opposite side from the tension of the spring 1", Plate 0 and the operating parts connected therewith are inactive when the check-rowers are in use. The seed which drops is conducted through the tubes L into the furrows, which are formed by the openers L and the cutters or colters L Within and near the lower end of each tube L there is a valve Z and an operating-rod Z is connected to such valve at its lower end and at the upper end is hinged to a crank on the crankshaft I. When the rock-shaft begins to move, it

lirst o Jens the valve allowing the char e of seed in the tube L to escape therefrom, and subsequently causes the seed-plate to deliver another charge to the tube, the valve closing before thelast-said charge can escape from the tube.

The check-row wire is guided to the fork H by the following devices: M is a normally horizontal guide-sheave situated directly behind the forked lingers M M, the three being situated to form the wire-passage m, and the wire has a rolling support from the pre. ence of the sheave, which is carried by a lever M which is pivoted to a suitable support at an intermediate point of its length and at its upper end is pivoted to a link M", which in turn is pivoted to a lever M, these parts providing a toggle connection for the sheave. A cord extending from near the operator connected to the lever M, and by means of these he can throw the sheave M from the closed position (see Fig. 6) to the open position (shown in Fig. 8) and in doing so permit' the wire to instantly escape, as is necessary at the end of each row, so that the machine can be turned, and accomplish this without leaving his seat. Behind the fork the wire is supported between a forward flanged roller N and a similar one, N, below and in the rear of said roller N. In order to guide the driver, a marker N is employed, supported on a bar N 2 at the rear of the machine.

When it is desired to use the machine for drilling instead of planting interrnittingly, a seed-plate like that in Fig. 14: is employed. It has a bevel-gear P, which meshes with a wheel P on a transverse shaft P, which extends from one seedbox to the other and is rotated by a chain P, receiving power from the shaft P. This shaft is mounted on the main frame and is rotated by the wheel p, which engages with a wheel 2, secured to the groundwheel A. It is provided with a series of different-sized wheels or cone-gears P2133194, with either of which the chain P can be engaged, according as a fasteror slower speed is desired. The shaft P (see Figs. 2 and 3) passes loosely through the wheelsp p 2" (preferably integral) and also loosely through a chambered sleeve P. In the chamber of this sleeve there is a clutch P, which is secured to the shaft and wh ich is adapted to engage with the clutchteeth P on the chain-wheel. P is a chambered sleeve on the opposite side of the wheel, which contains a spring P, which normally acts to press the clutch-teeth 1" of the chainwheel into engagement \vith'the clutch P.

At times it is desirable to prevent the chain and chain-wheel from moving, as ,when the machine is being turned at the end of a row. To accomplish this, I form on the sleeve 1 an arm P and a cam-like surface 12'' at its end (see Figs. 2 and 3) and combine with them opposing cams go", which are carried by an arm P", that rocks about the axis of the groundwheel. When the arms P'" P rock, which occurs when the runner-frame is lifted up,

the cams at p' p press the sleeve at P out' ward and push the chain-wheel away from the clutch P and thereupon the chain stops and the seeding mechanism is stationary; but as soon as the frame is lowered the cams 31 are so moved out of engagement that the spring at P can force the chain-wheel and.

the sleeve 1" in ward and produce engagement between the clutch and chain-wheel, when the drilling action will recom'mence.

When the check-row wire is not in use, it is Wound upon the reel Q. (Shown in Figs. 33 and 35.) It is mounted in a bow-frame Q, extending from the frame-bars 0 up to the drivers, seat. The reel has on one side a closed bearing and on the other side an open bearing q, Fig. 36, in which it is secured by amovable lock-arm q, normally held in place by the spring g The runner-frame is vertically adjusted relatively to the wheel-frame by the devices shown somewhat enlarged in Figs. 29 to 31. 'M- are brackets or standards secured to and rising from the axle I). The seat-support R is rigidly secured to these brackets. S is a footlever pivoted at s in the brackets '1' and extending forward and back from the pivot to points within reach of the drivers feet. At the front it is provided with a transverse pedal S and at the rear with a pedal S. It is flexibly connected to the runner-frame,

which supports the seeding mechanism, by

one or more links T, pivoted to the eye 0 at the rear end and joining the bars a of the runner-frame. hen the lever S is free to rock on the pivot at s, the weight of the forward part of the machine pulls down the link T and the front end of the lever S.

the lever against such rocking on the pivot, I employ a curved stop-bar U, practically To lock 1 concentric with the pivot at s, but capable of a limited oscillation on its pivot at U The upper end lies between and extends somewhat beyond the seat-bars R, and the lower end extends to or somewhat beyond the lowest point ever reached by the lever S. The bar U is provided with an adjustable stop U, against which the rear end of the lever S or some part connected therewith, such as the pedal S can engage, and when engaged the lever will be locked and the rear end prevented from rising. The stop U can be adjusted, as the rear edge of the bar Uis provided with a series of recesses a, with which the set-screw u can engage. When the runner-frame is in the position for planting or drilling, the parts last above described are in a position approximating that shown in Fig. 29, the stop U being in position to hold the frames as described when it works, but adjustable as above described. At this time the rear part of the runnerframe and the forward part of the wheel-frame tend to swing downward, and the bars a draw down the link T, which in turn pulls down the front end of lever S and forces up the rear pedal S against the stop U. If for any purpose it should be desired to let the runners drop deeper than is permitted by the stop U, the operator can with his foot disengagethe stop, whereupon the parts in front of the axle will tend to move downward; but when it is desired to take the runners up from the ground entirely it is done by the driver pressing down the pedal S which results in drawing up link T and elevating the runnerframe, and the lever S is locked in this position automatically by the bar U, which swings forward sufficiently far to have its free end come over the pedal S and thereafter prevent the latter from rising, which locks the runnerframe in its elevated position. To move the bar U, there is a lever V within reach of the operators foot, it being pivoted at '0 to the brackets '1. It is connected by a link V to the upper end of bar U. When it is desired to unlock bar U and lever S, slight pressure on pedal S is exerted with one foot and pressure on lever V with the other, the latter resulting in throwing bar U back, so that the pedal S can rise and the forward end of lever S descend, permitting the runner-frame to return to the ground for action.

I dispense with the hand-levers ordinarily used for adjusting the vertical position of the runner-frame relatively to the wheel-frame, the parts in this machine being so related with respect to each other that the driver can by his feet alone easily move the frames into any desired relative position; but to provide for moving the bar U by hand when occasion requires I furnish it with ahandle V, by which the driver can actuate it by hand when it'is inconvenient to do so with his foot.

There are links T which connect the arm P (hereinbefore referred to) on sleeve P 5 with the runner-frame or the lever S mediately or immediately, and when the lever S is moved up at the 'front end with the runnerframe these links T pull the arm P upward and turn the sleeve 'P on shaft P and compel the cams p and p to disengage the clutchteeth' at P P", after which the sprocket-wheels and chainwill be inactive. WVhen the runnerframe is again lowered, (in the way described,) the arm P rocks relatively downward, and the cams at 19 pass those at p again under pressure of the spring, and the clutch is engaged and the sprocket-wheels are rotated.

The peripheries of the wheels A A are cleaned by means of scrapers WV W, curved to conform to the said peripheries and attached to a sliding bar W. The latter has guideclips w, fitted to the side bars 0 of the steel frame and which permit it to slide bodily thereon.

V is a link connected to bar W and hinged to the crank 20 of a crank-shaft 10 which is rocked by a pedal-crank W within reach of the drivers foot, the rock-shaft being mounted in a bearing 20 From the foregoing description and the drawings it will be seen that the power or actuating devices both for intermittent plantin the frames of the machine, but are entirely independent of each other.

By such a construction and arrangement of parts as I have illustrated and described it is possible to simultaneously drill from one of the hoppers and plant intermittingly from the other.

I am aware that prior to my invention it has been proposed to provide a planter which could be arranged to plant seed intermittingly or continuously; but in all of the earlier constructions with which I am acquainted one or more members of the actuating devices were employed in both operations, and besides shifting the seed-plates in the hoppers it was necessary to either remove or disconnect some of the parts used in intermittent planting to adapt the machine for drilling.

With my construction in order to adapt the machine fordrilling it is merely necessary to change the seed-plate and to connect the link with the lower hole provided therefor in the valve Z which will maintain an open passageway through the conducting-tube L for the seeds.
